About CSV Cleaner
CSV Cleaner does the two repairs almost every export needs: it trims leading and trailing whitespace from every cell and header, and drops rows where every field is blank. That is the whole operation — one button, no options to get wrong.
Those two problems are what break an import most often. A trailing space turns "Berlin " and "Berlin" into two different groups, and a file that ends with blank rows makes a loader read empty records. For mojibake and broken characters use the Encoding Fixer, and for changing case or padding a column use Text Transform — both are linked below.
